Please, read this section carefully before installation; otherwise you likely won't be able to use sublime normally after installation.
Keymaps listed in readmes are disabled by default. You should add next line to your "User/Preferences.sublime-settings" file ("Preferences: Settings - User" in command palette) to enable those keybindings.
"sublime_enhanced_keybindings": true,
Sublime enhanced provides replacements for default sublime actions (e.g. navigation, search, goto line, save and other). Some of that replacements can work in really unobvious way. Please read "warnings" sections in "readme" for each package listed below carefully to avoid problems after installation:
Sublime enhanced remaps most of keyboard shortcuts so it will not play well if you have custom keyboard shortcuts in your "User/Default ().sublime-keymap". It will also not work properly if you have any plugins installed that bind keyboard shortcuts. In this cases you have to manually resolve hotkeys conflicts after installation by adding those hotkeys to "User/Default ().sublime-keymap".
Sublime enhanced is designed to improve code writing process but without getting used to it keybinding it will be probably harder to write code at first. I expect that time of adaptation to the replaced functions will be not more than 2-3 weeks.
Sublime enhanced is still in beta. That means that you can experience unexpected behaviors of any plugin included to this package.
